6. No Spam. Spamming is posting the same thing several times. "Bumping" (posting to move a thread up on the forum list) and cross-posting (posting the same thread in several forums) are examples of spam.
I would think the hardware store would have all the post you need, fence post, utility post... wooden post, mailbox post, tomato climbing post... no wait... the tomatoes climb the post- not the post climbing the tomatoes...
